LoRa Air Quality Sensor with temperature, CO2, relative humidity. MCERTS Certified Particulate Matter -PM1, 2.5, 4, 10 

Wireless Air Quality Monitor is a precision instrument that accurately measures up to 6 key environmental parameters including Temperature, Humidity, Particulate Matter (PM1, PM 2.5, PM4 & PM10), EPA Air Quality Index and Ozone.

Readings are transmitted to the cloud using long range LoRa wireless, where the data can be displayed and analysed.

  • Temperature (oC)
  • CO2
  • Humidity (%RH)
  • Particles PM 1, 2.5, 4, 10
  • Ozone*
  • EPA+ Air Quality Index (AQI) based on O3 and NOx concentrations*

*optional Sensor.

+EPA = US Environmental Protection Agency.

Measures key outdoor air quality parameters with outstanding accuracy and resolution using fully calibrated sensors.

 

MCERTS certified particulate matter sensor provides precise measurements of PM1, PM2.5, PM4 and PM10.

 

Ozone measurement down to single digit parts per billion (ppb) resolution using breakthrough self calibrating sensor arrays.

 

AOI sensor detects Ozone and Nitrogen Oxides as low as 20 parts per billion (ppb) to provide an Air Quality Index (AOI) based on international standards.

 

Device reveals outdoor air quality using leading edge digital sensors to provide high accuracy, long life, drift free readings without further calibration.
